  1. 1. The Human Spiral Ganglion

    Författare :Sven Tylstedt; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Otorhinolaryngology; human spiral ganglion; ultrastructural morphology; neural interaction; synaptophysin; connexin; membrane specializations; synapse; gap junction; tight junction; Otorhinolaryngologi; Otorhinolaryngology; Otorhinolaryngologi; Oto-Rhino-Laryngology; oto-rhino-laryngologi;

    Sammanfattning : Our knowledge of the fine structure of the Human Spiral Ganglion (HSG) is still inadequate and new treatment techniques for deafness using electric stimulation, call for further information and studies on the neuronal elements of the human cochlea. This thesis presents results of analyses of human cochlear tissue and specimens obtained during neurosurgical transpetrosal removal of life-threatening meningeomas. LÄS MER

  3. 2. The molecular basis of spiral ganglion neurons : diversity and development

    Författare :Charles Petitpre; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Hearing, one of our main senses, allows us to socialize, listen and enjoy sounds around us. The critical transmitters of the sound information are the spiral ganglion neurons (SGNs); located in the cochlea, they transmit the auditory signals from the hair cells to the brain. LÄS MER

  4. 3. Strategies in Cochlear Nerve Regeneration, Guidance and Protection : Prospects for Future Cochlear Implants

    Författare :Fredrik Edin; Helge Rask-Andersen; Peetra Magnusson; Maoli Duan; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Human vestibular nerve; Scarpa s ganglion; Stem cells; Nanoparticles; Nanocrystalline diamond; Oto-Rhino-Laryngology; Oto-rhino-laryngologi; Medical Science; Medicinsk vetenskap;

    Sammanfattning : Today, it is possible to restore hearing in congenitally deaf children and severely hearing-impaired adults through cochlear implants (CIs). A CI consists of an external sound processor that provides acoustically induced signals to an internal receiver. LÄS MER

  5. 4. Stem cell in-vitro strategies for the induction of sensory neurons for inner ear cell therapy

    Författare :Rouknuddin Qasim Ali; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The cochlea, a part of the auditory system, is a complex structure consisting of several different types of cells including hair cells and spiral ganglion neurons. In mammals, the regenerative potential of hair cells and spiral ganglion neurons is lost soon after the birth and damage to any of these cells causes sensorineural hearing loss. LÄS MER

  7. 5. Modulation of the HPA axis alters the sensitivity of the cochlea to acoustic trauma

    Författare :Yeasmin Tahera; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :HPA axis; corticosterone; glucocorticoid receptor; NFêB; spiral ganglion neurons; cochlea; acoustic trauma; paraventricular nucleus;

    Sammanfattning : The hypothalamic pituitary adrenal axis (HPA axis) regulates nearly all neuroendocrine responses of the body. An active HPA axis is crucial to maintaining homeostasis. An altered reactivity of the HPA axis can affect several physiological systems including the auditory system. LÄS MER
